When should hot foods placed in a refrigerator for cooling be covered?

Hot foods should be covered once they reach 41°F or below to prevent condensation and the growth of bacteria. At temperatures above this threshold, covering hot foods can trap heat and moisture, inadvertently raising the temperature inside the container. This scenario can create an environment conducive to bacterial growth, as pathogens thrive in warm, moist conditions. Therefore, allowing the food to cool to a safe temperature first ensures that it cools rapidly and remains safe for consumption. Covering the food at the proper time not only aids in maintaining food safety but also adheres to best practices for food handling and storage.
